Mouth ulcers, also called canker sores, are small and painful sores that form inside the mouth. Although they are usually harmless, they can cause discomfort and make eating or speaking difficult. Fortunately, several natural remedies can help alleviate pain and speed up healing. In this blog post, we will explore what mouth ulcers are, their causes, and their symptoms, and provide you with 15 effective home remedies to cure mouth ulcers fast.

What is a Mouth Ulcer?

A mouth ulcer is a shallow sore or lesion that forms inside the mouth, including the tongue, gums, inner cheeks, or lips. They are usually round or oval-shaped, with a white or yellowish center and a red border. These painful sores can vary in size, making eating, drinking, or brushing your teeth uncomfortable.

Types

1. Minor Aphthous Ulcers

Such mouth ulcers are the most common, with 80% of cases due to this type. Small, round, or oval aphthous ulcers have a white or yellow center surrounded by a red border. They usually are found on the inner part of the lips, cheeks, or under the tongue. These ulcers, though they may be painful, generally heal spontaneously within one to two weeks without scarring.

2. Major Aphthous Ulcers

Although less prevalent, major aphthous ulcers are bigger and deeper than minor aphthous ulcers. They may be more painful and may take several weeks to heal. The major ones lead to scarring and are prone to recurrence. They typically involve the soft palate, the back of the throat, or the bottom of the gums.

3. Herpetiform Ulcers

Herpetiform ulcers, contrary to their name, have nothing to do with the herpes virus. They are defined by aggregates of a number of pinhead-sized erosions that fuse to create large, irregular-looking lesions. Though in themselves they are small, each of them, the number of them in a group, makes a considerable and painful ulcer. However, herpetiform ulcers occur less often but are more persistent than minor aphthous ulcers.

Causes

The exact reason for mouth ulcers is not always known, but many factors can play a role in causing them.These include:

  • Injury or trauma to the mouth, such as accidental biting or brushing too aggressively.
  • Certain foods or substances, including acidic or spicy foods, citrus fruits, and tobacco.
  • Nutritional deficiencies, particularly in vitamin B12, iron, or folate.
  • Hormonal changes, such as those that happen during menstruation.
  • Stress or emotional factors.
  • Some health conditions, such as celiac disease or inflammatory bowel disease.

Symptoms

Mouth ulcers typically present the following symptoms:

  • Pain or discomfort in the affected area.
  • Sensitivity to hot, spicy, or acidic foods.
  • Swelling or inflammation.
  • White or yellowish center with a red border.
  • Difficulty in talking, eating, or drinking.
  • A tingling or burning feeling before the sore develops.

Home Remedies

  • Saltwater rinse: Dissolve one teaspoon of salt in a glass of warm water. Gently swish the saltwater mixture in your mouth for about 30 seconds, then spit it out. Repeat this rinse several times a day. Saltwater helps reduce inflammation, cleanses the ulcer, and promotes healing.
  • Honey: Apply a little raw honey directly on the ulcer using a clean finger or a cotton swab. Honey contains natural antimicrobial properties that can help stop infection and ease pain.
  • Coconut Oil: Take one tablespoon of coconut oil and swish it around in your mouth for a few minutes, making sure it covers the ulcer. Spit out the oil afterward. Coconut oil has natural anti-inflammatory and antimicrobial effects that can help promote healing.
  • Aloe Vera Gel: Extract fresh aloe vera gel from an aloe leaf and apply it directly onto the ulcer. Aloe vera has healing properties, including anti-inflammatory and antimicrobial effects, which can accelerate recovery.
  • Chamomile Tea: Brew a chamomile tea bag in hot water and let it cool down. Use the cooled tea as a mouth rinse and swish it in your mouth for around 30 seconds. Alternatively, you can apply a soaked chamomile tea bag directly onto the ulcer. Chamomile has calming effects and may help lower inflammation and ease discomfort.
  • Baking Soda: Mix one teaspoon of baking soda with a small amount of water to form a paste. Apply the paste to the ulcer and leave it on for a few minutes before rinsing your mouth with water. Baking soda works by reducing acidity in the mouth, easing inflammation, and helping the healing process.
  • Sage Mouthwash: Boil fresh sage leaves in water, strain the liquid, and let it cool. Use sage-infused water as a mouthwash, swish it in your mouth for about 30 seconds, and then spit it out. Sage has natural antimicrobial effects that may help in the healing of mouth ulcers.
  • Tea Tree Oil: Dilute tea tree oil with a carrier oil, such as coconut oil, and apply a small amount to the ulcer using a cotton swab. Tea tree oil possesses antimicrobial properties that can help prevent infection and aid healing.
  • Vitamin E Oil: Open a vitamin E capsule and gently apply the oil directly to the ulcer. Vitamin E contains antioxidant and anti-inflammatory effects that may help ease pain and support healing.
  • Ice Therapy: Suck on ice chips or place a cloth-wrapped ice pack on the affected area. The cold temperature helps numb the pain, reduce inflammation, and temporarily relieve discomfort.
  • Papaya: Cut a fresh slice of papaya and place it on the ulcer for a few minutes. Papaya contains enzymes like papain that may help support healing and lower inflammation.
  • Clove Oil: Use a cotton swab to gently apply a small amount of clove oil to the ulcer. Clove oil has natural pain-relieving and antiseptic properties that may help reduce pain and fight bacteria.
  • Vitamin B12: Take a vitamin B12 supplement or consume foods rich in vitamin B12. Vitamin B12 is essential for maintaining oral health and may support the healing of mouth ulcers. Foods rich in vitamin B12 include fish, meat, eggs, and dairy products.
  • Maintain Good Oral Hygiene: Brush your teeth gently with a soft-bristled toothbrush, carefully avoiding the ulcer. Use a toothpaste that does not include sodium lauryl sulfate, because this ingredient may irritate mouth ulcers. Maintaining good oral hygiene can reduce irritation and support faster healing.

Prevention

Mouth ulcers cannot always be prevented, but you can lower the risk by following some simple steps.

  • Eat a healthy diet – Include fresh fruits and vegetables in your meals. Make sure you get enough vitamins and minerals like vitamin B12, iron, and folic acid. Drink enough water to keep your mouth moist.
  • Avoid trigger foods – Stay away from foods that can irritate your mouth. These include spicy, acidic, hard, or crunchy foods. Try to notice which foods cause ulcers and avoid them.
  • Manage stress – Stress can increase the chances of mouth ulcers. Practice relaxation methods like yoga, meditation, and proper sleep.
  • Avoid harmful habits – Do not smoke or drink too much alcohol. Also, avoid biting your lips or cheeks and limit chewing gum.
  • Regular dental checkups – Go to your dentist regularly for routine cleanings and checkups. If an underlying health problem is causing ulcers, treating it can help prevent them from coming back.

Who to Consult?

For mouth ulcers, consider consulting a dentist or oral medicine specialist. When necessary, your primary care physician can guide you and send you to a specialist. Dermatologists can be helpful if ulcers are associated with skin conditions.
